Digital Manometer: uses no oil and detects pressures directly. Which option correctly identifies this instrument?

• A. Inclined Manometer
• B. Manometer
• C. Digital Manometer
• D. Thermoanemometer

Answer: (C)

Direct electronic pressure sensing with a digital readout defines a digital manometer. It uses a solid-state pressure sensor to convert pressure into an electrical signal and displays the result digitally, with no oil in the sensing path. Traditional liquid-column manometers, including inclined ones, rely on a fluid column and indicate pressure by changes in liquid height, not a digital display. A thermoanemometer measures air flow (velocity) and temperature, not pressure. So the instrument described is the digital manometer.
